The distance Laura slides on the newly waxed floor is 15.3 m.

What is kinematics equation?

The equation used is derived from the work-energy principle, where the work done by friction is equal to the change in kinetic energy.

The distance Laura slides on the newly waxed floor is given by kinematic equation:

d = v²/2 μ g

where:

d is the distance Laura slides,

v is the initial speed (6 m/s),

μ is the coefficient of kinetic friction (0.12),

g is the acceleration due to gravity (approximately 9.8 m/s²).

v = 6 m/s

μ = 0.12

g = 9.8 m/s²

d = 6²/2*0.12*9.8

d = 36/2.352

d = 15.3 m

Therefore, the distance Laura slides on the newly waxed floor is 15.3 m.
